Between the two I like [name_f]Seraphina[/name_f] quite a bit more and I think [name_f]Seraphina[/name_f] [name_u]Shay[/name_u] has a nice ring to it!
I’d spend some time playing around with the search engine on here. There are a lot of lovely names out there that aren’t in the social security top 1000 and it sounds like you’ve settled on these two out of exasperation more than anything.
I think [name_f]Seraphina[/name_f] [name_u]Shay[/name_u] is a great combo! I especially like that you can get many nicknames out of it like Phina, Phi and [name_f]Sera[/name_f]. With [name_f]Lilah[/name_f] I can’t think of any nickname options, whether or not that aspect is a pro or a con to you. Beside nicknames the reason I like [name_f]Seraphina[/name_f] more is because [name_f]Seraphina[/name_f] [name_u]Shay[/name_u] flows better than [name_f]Lilah[/name_f] [name_u]Shay[/name_u] (and sounds like a princess!).
I love [name_f]Lilah[/name_f] Sh@y! It has a sleek and sophisticated vibe. I personally prefer to choose a name that I love and use it exclusively rather than call her by a nickname so I agree with pp that it depends on whether you are a nickname person. [name_f]Seraphina[/name_f] is long so it is likely that she would end up with a nickname whereas I think you could call [name_f]Lilah[/name_f] by her given name.
In general, I prefer [name_f]Lilah[/name_f], but combined with your surname, [name_f]Seraphina[/name_f]/[name_f]Serafina[/name_f] is irresistible. I say go for it!
I think they are both lovely names! I’m leaning towards [name_f]Seraphina[/name_f]… [name_f]Seraphina[/name_f] [name_u]Shay[/name_u] definitely does sound great! But you really can’t go wrong either way.
With your surname, definitely [name_f]Seraphina[/name_f]. It just flows, whereas lilah shay feels kind of awkward and sounds clunky.
But dont pick anything that you dont both love, when you find the right name you will both know it. And if you pick a name you dont both love, as life goes on you will find you dont end up using her name much of the time!
Given you been basically all through the lists here, Maybe think outside the box and think about things you want for your daughter, and use those to do word searches, in English and other languages…you would be surprised how many words in other languages would make pretty english names and have thoughtful, meaningful translations to boot!
I think [name_f]Lilah[/name_f] [name_u]Shay[/name_u] sounds better but I like the name [name_f]Seraphina[/name_f] more! However, like others have said, [name_f]Seraphina[/name_f] [name_f]Lilah[/name_f] [name_u]Shay[/name_u] is beautiful and a wonderful option.
